(GRANTED UNDVR THE PROVISIONS F THE ACT 0F MARGH 3, 1921, 4l.. STAT. L., 1313.)

To all whom it may concern:

Be it known that I, ALEXANDER v. Ro'rnn, a citizen of' Germany, residing at Berlin- Wilmersdorf, Germany, have invented certain new and useful Improvements in Cinematographic Apparatus (for which I have filed applications in Germany, March 29, 1919; Switzerland, February 25, 1920; Luxemburg, February 26, 1920; Denmark, March 2, 1920; Sweden, March 5, 1920; Norway, March 9, 1920; Hungary, June 19, 1920; Austria, June kia, June 25, 1920; Netherlands, June 29, 1920; Italy, June 30, 1920; Spain, July 2, Poland, July 6, 1920; Great Britain, July 6, 1920; Belgium, July 9, 1920; Japan,.September 18, 1920), oi which the following is a s eciflcation.

When taking cinemato rapihic views at a short distance, which un er certain circumstances may only amount to a few feet, one oi' the chief diliiculties encountered resides in securinggood lights for the object, in particular as the rather cumbrous apparatus is apt to throw shadows. This fact will be particularly noticed when using artificial means of lighting and when employing long films which lat-ter render big spool boXes necessary.

In accordance with this invention the obtaining of satisfactory light is materially facilitated by the fact of the said spool boxes being distanced from the cinematographic apparatus proper, connection between the two being established by aid of special film conducting members. vBy these-means the advantage is secured that the cinematographic apparatus proper may now obtain the smallest possible dimensions so that it will henceforth be unable to impair the lights thrown on the object to any notable degree. The invention will be found to be of special importance when filming surgical operations, or the like, where it is of essential the operation shall have full benefit of the light, and that'moreover he and his assistants shall be embarrassed in their movements as little as ossible by the presence of 50. the apparatus'. or this kspecial purpose,

which several auxiliary devices to be explained hereinafter are intended to serve,

24, 1920; Czechoslova-- consequence that the surgeon carrying out the separation of the apparatus proper from the film boxes is preferably carried to such lengths that the latter are even disposed out'- side of the operating-room altogether, say, for example, above the ceiling from which the apparatus is suspended. From the viewpoint of asepsis this is of course a point of great moment as by these means the dust, which will arise when the films are renewed, is kept out'of the operating-room. It will further be in the interest of asepsis that touching the apparatus for the purpose of adjusting the same be avoided as far as possible. F or this purpose all the motions required or the adjusting, such as the raising, iuclining, shifting, may be carried out by means of a motor or motors, which may even be accomplished without requiring the operator to use his hands for the purpose of carrying out the switchoperations, for which pedal switches may be provided. y

Various embodiments of the subject matter of this invention are shown by way of example in the accompanying drawings, in which: Y

Fig. 14 shows diagrammatically the electrical connections of the differenty motors and their controlling means applied tothe construction'of Fig. ,f

Fig. shows also diagrammatically an arrangement in which all the motors are disposed outside of the operating room. l

Referring to Fig. 1, the cinematographic apparatus proper 1 is connected by means oftwo channels 2 and 3 with the film storage box or magazine 4 and the box 5 in which the film is wound up. The film 6 runs oli" from the spool 7 arranged in the box 4 through the channel 2 to the apparatus 1, and thence through the channel 3 to vthe winding spool 8.' This latter may obtain its means of a rope or belt 96 fromv the same motor 9 serving to drive the Jr'eed gear mechanism of 'the apparatus by means not extend right up enlarged extension channels o f a rope or belt 97. The entire device Ymay elther be set up on a stand or tripod or else be hung up in any convenient manner. If

the entire system be rigid then, as obvious,

any adjusting motion of the apparatus l will be followed by the lm boxes and the guide channels. In accordance with the modilied form of construction shown in Fig. 2, this necessity may be obviated by the apparatus 1 being articulated to the channe the channels are placed in direct juxtaposition, the film being transported along said from the apparatus by the intervntion of rollers 10, 11. 'I he channels do to the apparatus, connection being established, on the one hand, by means of a support 12 articulated at 14 tothe apparatus, on the other hand, by means of a bellows 13 to shut out the light. In Fig. 2a the apparatus is shown in a displaced position.

Subject to Fig. 3, the apparatus 1 is sus pended vto oscillate in a vertical plane, by a rod 15 with aid of a link member 14. The rod 15 for its'part is adapted to rotate within a tube 17 suspended from girders 16. The adjustment ofthe apparatus to any required height is effected by means of a sleeve 18, the iange 19 of which is inserted. in an 20 of the tube 17. At its free end the sleeve 18 is slotted so as to constitute a clamp adapted to {irmly secure the suspension rod 15. The apparatus, the

i height of which has been adjusted in the manner described,

may beroscillat'ed aboutA its vertical axis bythe rotation of the sleeve with .the rod 15 within the iange 20. In lorder to facilitate the raising an lowering operation,4v and also in order to render it impossible for the apparatus to suddenly drop on the clamp 18 loosening its hold, the weight of the apparatus and of the suspension rod 1'5 along with the rest s 2 and 3. In this form of execution inrosa? of the parts connected thereto, may be suitably balanced by the provision of va counterweight 40, merely indicated in the drawing,

as of course itwould have to be ar larger..

The raising and lowering operation may be carried out by motor means,say, for example, by aid of an electromotor 41 acting by the intervention of a worm gear 42, 43 on a guide pulley 44 of the tension member (chain) 39 running to the counter-weight 40.

The lilm magazlne box 4 and the winding box 5 are disposed above the glass covered ceiling 45 o .an operation-room. The film channels 2 and 3 are arranged to pass through guide members 47 48 of a plate 46 adapted to close from below a ircular openin 49 ormedin the glass covered ceiling, said plate being disposed so as to freely rotate on an annular flange 50 of the tube 17. This arrangement affords the possibility of rotating the apparatus suspended by the' rod 15, along with the channels 2, 3 and the film' boxes 4,- 5 mounted thereon, by the intervention of the guide members 25, around its vertical axis; and while absolutely maintaining the closure between the operati'n4 -room and thev sky-light chamber. The guides 47, 48 additionally serve to strengthen the film channels to the degree required. The arms 51 arranged at the lower end of Y. the rod 15, and which are adapted'to embracethe lower Lextremities of the channels 2, 3, are intended to serve a like purpose.

In order to enable .the apparatus to be oscillated along a perpendicular plane about the fulcrum 14, there may be arranged, as shown on the left hand side of Fig. 3, at the point of transition between apparatus 1 and the film channels a bellows 52; or else, as disclosed in same figure on the-right' hand side, a knee-joint 53 may be employed. p

Both arrangements enable the apparatus to be oscillated without causing any substantial alteration in the length of the film section disposed intermediatev the film boxesl ing. d The film boxes 4, 5 which are slid into the channelled guides 25 are screwed to supports 26 carried by ing upwardly out of the tube 17.

As shown in the drawing, a motor 9 mounted on the`v apparatus 1 serves to drive the end of the rod 15 project rangeinen t.

tact the ilin feed ear, while another motor 28 mounted on t e support 26 is destined to drive the spool within the film storing box 5. desired, the rotation of the apparatus about the rod may be e'ected by means of a motor 29 with the intervention of a worm gear 30, 31. ln thatevent the worm wheel 31 as shown, be connected so as to rotate with the rbd 15 displaceable within it, by 'means of a groove and tongue ar- 'lhe said wheel is secured against longitudinal displacement by the the flange 63 being adapted to engage a groove formed intermediate the upper front end of the tube 17 and a ring 64 lined thereon. The pendulum motion of the apparatus about the fulcrum 14 may likewise be obtianed `from a motor 32 by the intervention of a worm gear arrangement 33, 3d.

The channels-2, 3 are represented as being provided with removable lids 86, 87, 88, 39 at suitable places so that they may be opened in order to remove the film dust col lecting therein and also to facilitate the in sertion or' the ilm.

ln the construction just described, the oscillation of the apparatus about the vertical anis is limited by the fact of the girders 16 crossing the path of the film channels 2, 3. This may be obviated in that, by making the lihn channels 2, 3 suitably stronger and b abandoning the connection of the iilm boxes with the rod 15, the tube 17 is extended in the upward direction,- as shown in Fig. 4, and lodged above the uppermost position which the boxes may assume on the girders is.

1n the form of the invention shown in Fig. 5, which essentially corresponds to the arrangement according to Fig. 2, the film 6 is run upward through the suspension tube 15, in order to" dispense with the arrangement of separate iilm channels adapted to be raised outside of tube 17. lThe method of suspension is that a 'pertaining to Fig. 2, namely by means of epending arms 12, and the light being shut out by the aid of a bellows 13 connecting-the end of the tube 15 with the apparatus.

Inail the' apparatus hitherto described, the optic axis, which in its centremost posi- 'tion is perpendicularly disposed, cannot be brought intoa horizontal position by the oscillatory motion of the apparatus. The arrangement shown in Fig. 6 obviates this drawback by the arms 12 supporting the apparatus 1 being inclined downwards at an 'angle of about 45 from the tube 15, with the result that the apparatus may now be shifted by an oscillatory motion of always from the inclined central position, corresponding to the direction in which the arms point, into a horizontal and perpendicular position. e y

proper axial position.

Fig. 7 discloses a further modified form of the invention. Inthis case the feed gear of the apparatus 1 operated by the motor 9 is housed in a cylindrical casin of the bottom of which the objectlve 22 protrudes. The said casin is lodged in a ring 56 screwed by means o? a threaded connection 57 into the lower extremity of the tube 15. This ring is provided at its circumference for the passage of the objective vwith a slot 58 of such peripheral extent that the cylinder may be readily rotated by an angle of 90 from the vertical position thereof bythe action of motor 32 and screw gear 33, .34.. The film is fed forward and returned through a channel 23 disposed at one side of the tube 15, Said channel being adapted to be raised and lowered conjointly with the tube 15 within the guide tube 17 under the inrluence of the motor 41. A circular 55, out

plate 60, surrounding the tube 15 and the channel 23, is adapted to loosely yengage the internal face of the tube-17, a bush 61 screwed up in front acting as its lower support. YWhen the tube 15 `with the apparatus depending thereon effects a rotation, the said circular plate 60 Again, when the said tube is either raised or lowered, both tube and ilm channel 23 slide along the plate 60, which, as will now be understood serves to secure the tube 15, in any position which it may assume, in the disposed at the upper end of the tube 17, serves, as i'n the construction according to Fig. 3, a like purpose;

For the purpose of feeding the Elm 6 from the apparatus 1 into the channel 23, it is guided along on rollers 67, 68, 69 and 70, 71, 72, respectively. To keep the lpassage free in any position which the apparatus 1 may assume, the cylinder 55, serving to accommodate the apparatus, is provided at its peripheryk with a slot 7 3 extending for about a third of its circumference and being somewhat broader than the film. The ring 56 for its part is by so much broader than the slot 73 that there will remain a covering Suilicient to reliably shut out the light. The light excluding closure may moreover be still further improved by edge strips 74 being arranged around the cylinder 55 adapted to place themselves in front of the slit remaining between the cylinder and ring.

In the construction shown, and correspondingto the employment of a single channel 23 in which the two film sections 6, 6? are disposed the one to the rear of the other being distanced from eachother by antifriction rollers 93, the two Hlm boxes 4 and 5 are superposed. As shown in Fig. 13, however, the boxes may alsowith a single film channel be juxtaposed at the same level by detlecting 4kone of the film sections, Afor instance 6* by means yof obliquely disfollows this motion The wrm wheel 31,

posed rollers 98, 99, Fig. 13. lBesides, in order to render every section of the film within the channel accessible, and this .independ- ,ently from the other, there may be arranged, as Fig. 11 shows, separate film jchannels 2, 3 extending symmetrically to each other intermediate the-tubes 15 and 17, so that the mutual arrangement of the film boxes will eFssentially be the same as that disclosed in n the drawing there is nally shown a special device adapted to enable the focusing of the picture and the sharpness thereof to be adjusted without rendering it necessary for the apparatus to be opened. lin this case it is assumed that the section ofthe film hap-l pening to be located in front of the objective is being used as a screen. 'lo the rear of the film there is arranged at an angle of a mirror 75 (Figs. 7 and 12). Within the oppositely disposed front wall of thecasing there is arranged to oscillate a knee joint 7 6, within the angle of which there is disposed a reecting prism 77 adapted to redect the picture in the direction of the long.

limb of the joint (Fig. 12). At the end of this latter isv arranged an ocular 78 through which the operator will thus be enabled to View the picture projected on to the film. By reason of the fact that the knee joi-nt 76 is adapted to oscillate, the picture may be viewed with all convenience regardless of the height or angle to which the apparatus has been adjusted. rlhe numeral 79 denotes a cap or closure after the manner of those used for objectives, -and which is suitably vkept closed by spring action as long as the hand grasping the ocular does not engage a member, not shown, serving to edect the opening. The focusing device is preferably connected to the knee joint in such manner that the rotation of a disc or hand wheel 80, disposed to the rear of the ocular, is transmitted by aid of the tube 81, of bevelled wheels 82, 83, and of other suitable intermediate members on to the adjustable portion of the apparatus. As the tube 81 is'quite loosely mounted on the tube 7 6, as may be seen from the section in Fig. 12, it rotates very gently relatively to said tube and the toothed wheel 83. Hence the ocular may be adjusted, without this operation being impaired. or disturbed when the tube is dropped into its vertical position.

ln view ofthe long distance the film is obliged to travel, it will prove essential to interrupt the motion of the apparatus before the film has completely run oid' from the magazine spool, to enable the fresh film to be attached toV the end of the one just run off. This operation may be e'ected in a simple manner by aid of an automatic electric switch 84 (Fig.

onthe circumference of the film. spool, said respectively a distance therefrom,

camera and means 7), the action of whichv ismadc dependent upon a feeler 85 reposing temeer ing motors to enable the adjusting motions to be ,brought to a stop when the terminal positions are reached.

ln the different constructions described the switches for the various motors may be arranged at some central place, as shown in Fig. 14, preferably within reach of the feet of the operating physician so that he may 'thus control the apparatus without using his hands. Fig. 14 shows the connections applied to the construction of Fig. 7.. a., b are the mains. From the main a branch conductors c, d, e, f lead to the motors 41, 28, 29, 32 respectively. The motors 41, 29 and 32 are also connected by wires g, h, i through switches Z, m, n with the main b, so that by closing one of these switches the corresponding motoris operated. The motor 28 is connected by wire y with motor 9 from which a conductor leads to a switch 0, by means of which therefore the motors 28 and 9 which are disposed in series, are simultaneously put in and out of operation.

llf it be desired to 'obviate the necessity of arranging the motors 9, 32 within the oper'- ating-room, then the said motors may be disposed above the ceiling 45, Fig. 7 and the' respective motions of the motors be transmitted by aid of intermediate gear-ings. 1t will in such a case be found suitable to drive the feed gear by means of the motor 28, as feed gear and winding spool must always. synchronize in their motions. rlhis arrangement is shown in Fig. 15 wherein the connection of the motor 28 with the driving shaft of the feed gear is obtained bvmeans of bevel gear 90, vertical shaft 91 and flexible shaft 92. The motor 32 is mounted at'the upper end of the rod 15 by means of a support 101 and drives the worm 33 by means of vertical shaft 94 and bevel gear 95. l
